“…Practice shows that breakthroughs in the technological development of the world are carried out, as a rule, without any connection with the people's standard beliefs about the future. Therefore, let us enumerate a few "non-standard" scientific approaches to mining technologies [Bondarenko et al, 2017;Falshtynskyi et al, 2018].…”

The influence of the humanitarian component (sacred, religious, social factors) on the origin and initial development of mining activity, metallurgy origin, the first natural and technical knowledge accumulation and application forms are considered. The hypothesis of the metallurgy occurrence in the stable communities of primitive miners is considered. The ideology component of important technological inventions, created in an environment where both these phenomena were extremely close, is shown. The organizational forms of mining activity in which sacred factors played an extremely important role from archaic mining communities to medieval religious orders (in particular, Cistercians) were analyzed. The role of traditions, beliefs and professional knowledge in the formation of the special mining communities' nature from ancient time to the Middle Ages, their heritable resistance and isolation have been revealed. The possible ways of future mining progress are described, for which the scientists' and entrepreneurs' substandard ideas and predictions are used.

Topical issues concerning the possibilities of effective energy generation on the basis of Ukrainian mining enterprises have been highlighted. Attention is drawn to one of the most challenging tendencies of nontraditional energy sources development in the process of wind-driven powerplant use. The plants consume energy of technogenic air flows. Operation schemes and engineering solutions as for the possibilities to involve nontraditional sources of energy resulting from operation of technogenic objects and industrial structures of enterprises (i.e. stopes, mine dumps, industrial facilities etc.) in power balance of a mining enterprise have been demonstrated. Energy efficiency of the wind-driven powerplants in the context of different operation schemes aimed at utilization of energy of technogenic air flows has been analyzed. Output of a wind-driven system as a component of technological segment of a mining enterprise making it possible to meet 20 to 44% of its power demand has been determined. The objective of the paper is to substantiate process solutions as well as technical and engineering ones as for the obtaining nontraditional energy sources basing upon introduction of wind-driven power plants.

“…Maximum admissible concentration of harmful substances in the water is the maximum concentration, which does not have a direct or indirect impact on the health of the population and the next generations, that is determined by modern methods of research with its impact on the human body throughout life and does not impair the hygienic conditions of water. Features of harmful substances manifest in their adverse effect on the processes of natural self-purification of water reservoirs (general sanitary index), organoleptic properties of water (organoleptic index) and population health (sanitary toxicological index), characterized by limiting and threshold concentrations [6]. The admissible threshold harmful concentration by the organoleptic features is the maximum concentration in water at which changes of organoleptic properties of water are acceptable for the population.…”

Surface run-off is water from rain and snowmelt flowing from the territory of industrial enterprises. The part of surface run-off in the total volume of discharged wastewater from the coal industry is 2%. Their volume depends on the amount of rain and melt water, as well as the size of the sites of industrial enterprises. The objects of surface run-off contaminants in the Novovolynsk mining area are: outdoor coal and concentrate storages, colliery spoil heaps, sludge and tailings, crushing compartments, storages fuels and lubricants, points of railway cars loading and unloading, cable cars, boiler installations, etc. On the territory of the Novovolynsk mining area besides the wastewater a huge amount of mining waste is formed. It is stored on flat heaps, adjacent to the area. Coal also accumulates on flat dumps. The surface run-off from the area of the flat heaps may contain chemical compounds. Surface water from the mine area is not purified, although in terms of quality, it is highly polluted. During investigation period the Novovolynsk mining area the storm run-off from their territory contained more than 15,000 mg / ml of suspended substances and up to 500 mg / ml of petroleum products [4]. Spoil heaps are the main sources of surface run-off contamination by suspended solids, mineral salts and heavy metal ions. Thus, the amount of suspended solids in rainwater reaches 12000 mg / l and in meltwater - up to 50,000 mg / l, the total salt content reaches 8000 mg / l. The maximum amount of iron is more than 7550 mg / l. It is found in the meltwater from the spoil heaps of almost all mines in the Novovolynsk mining area. The composition and concentration of pollutants in coal storage water runoff doesn't differ too much from the spoil heaps water run-off. An extremely important factor of man-made impact on the sanitary status of natural water bodies is the pollution of the water-intake areas around coal and mining enterprises by chemical elements, especially during polymetallic ores development [2].
